Western Eurasia witnessed several large-scale human migrations during the Holocene1,2,3,4,5. Here, to investigate the cross-continental effects of these migrations, we shotgun-sequenced 317 genomes—mainly from
population size:the number of individuals in the population population density:how many individuals are in a particular area population growth:how the size of the population is changing over time. If population growth is just one of many population characteristics, what makes studying it so important...
Posted on August 1, 2024 | Comments Off on Polar bear “boom” reported in East & Southwest Greenland comes with the usual problems Reports over the last week of an unexpected abundance of polar bears onshore in East and Southwest Greenland have locals and tourists concerned. The former Pr...
2012). The PVA results of the Western Lowland Gorillas (Gorilla gorilla gorilla) suggested that the reintroduced gorilla populations have a reasonable chance of persistence over 200 years, but the reinforcement of the populations could significantly improve probabilities of population persistence and ...
from 1940 and also gives projection till 2040. A glance at the graph makes it clear that Japan will have more percentage of the aged population in the future despite its fewer percentage of this population in the early 40s and one-fourth of the world population will ...
This overtly genealogical approach to population genomics, focused on an observed sample of allele copies in the present day and tracing a tree backwards in time from these, has given rise to much new work in population genomics over the past 25 years, collectively known as coalescent theory (...
"A more detailed analysis shows that in 1900 there was a total of 1.6 billion who inhabited the world." There are some more inaccuracies. Asia is represented by 60% of the pie graph. If you divide 60/100, that equals 3/5 of the population and not one third or 1/3. I would encour...

Despite bread wheat serving as a keystone crop worldwide, the population history of bread wheat and its relatives, both cultivated and wild, remains elusive. By analysing whole-genome sequences of 795 wheat accessions, we found that bread wheat originated from the southwest coast of the Caspian ...
the south-west, there is a smaller group of coralline islands known as the Amirantes, while the Outer Islands in the south include the Aldabra and Farquhar groups. These Outer Islands are also coralline in origin and include several atolls, the largest being Aldabra Atoll, a UNESCO World ...
